8 cups a day is the kind of advice usually give by a urologist in any Chinese hospitals, mainly because they have witness so much agony in calculus cases. But once away from hospital people tend to forget about doctors' advice. We don't really tend to think that far ahead.
If a Chinese person gets kidney stones for drinking to little water or high-calcium water, s/he just goes under the lithotripter and gets rid of them.
A lot of us get sucked into study/work so deeply that even nature's calls get in our way. So some of us avoid peeing as much as we can.

It takes seconds to load a book in my iPad from a cloud account.
This moment I have in my Baidu Cloud about 1800 books in .epub format.
Surely we can find one or two classics by anyone's standard.
I downloaded them on torrent sites like verycd.com, kickass.to, and Baidu Cloud share.
Guilty as charged. But this shall not be my official confession.
PS the books usually come both in epub for iPad and mobi for Kindle.
